Thanks, Indeed it does show up in the photos. I'm going to assume that the fix would be more expensive than a new/used camera body?
Did you look at the photos on a computer, or in the camera? Do you see those lines when you browse the camera menus?

This is important. It could be your LCD which is annoying but not harmful to the actual photo.
It is very important. If you are viewing photos in the camera, try to zoom in to see if that makes a difference. I think you may actually have a LCD issue.
